RGXII Ductile Iron Valves for Sewage & Effluent

Air valve technology that delivers superior surge protection and exceptional low pressure sealing.

“ANTI-SURGE” SEWAGE AIR RELEASE & VACUUM BREAK VALVES

The VENT-O-MAT Series RGXII sets the benchmark for performance and reliability in air release and vacuum break valves. Designed with an advanced anti-surge mechanism, it prevents pipeline damage caused by high-pressure transients and ensures controlled filling and discharge under all conditions. Its compact design is perfect for installations with limited space, while the full port opening feature minimizes resistance during draining or surge events, preventing negative pressure within the pipeline.

With precision low-head sealing, the RGXII is effective even at pressures as low as 3 psi (21 kPa), making it ideal for systems with low operating pressures. Built to last, it comes with a fusion-bonded ductile iron body or corrosion-resistant stainless steel (304/316), ensuring durability in even the harshest environments

The Vent-O-Mat RGXII revolutionizes pipeline management by effectively addressing common issues such as air entrapment, leakage, and pressure fluctuations. Its innovative design ensures optimal performance in various applications, from municipal water systems to industrial processes. By investing in the RGXII, you’re not just purchasing a valve; you’re securing a reliable, efficient, and long-lasting solution for your pipeline infrastructure.

Prevention of Leakage at Low Pressures: The patented low pressure sealing design ensures that the valve remains leak-tight even at low pressures, preventing any leakage of fluids. Leaks in effluent and sewage systems can pose significant safety and environmental hazards, including contamination and municipal fines.
Cavitation is prevented by vacuum protection: The RGXII valve has large orifice diameters that equal the nominal size of the valve, ensuring minimal resistance to air intake and preventing negative pressure within a draining pipeline.

Features

Advantages of Vent-O-Mat RGXII “Anti-surge” Air Release & Vacuum Break Valves Are:

Anti-Surge Mechanism: Designed to prevent pipeline damage from high-pressure transients associated with high-velocity air discharge. This mechanism also allows for controlled filling of the pipeline, maintaining controlled discharge at all times.
Compact Design: The RGXII is more compact and shorter without compromising the pressure rating of the valve, making it suitable for installations with space constraints.
Full Port Opening on Negative Pressure: During pipeline draining and instances of surge, the valve allows the intake of air to the full nominal bore, ensuring minimal resistance and preventing negative pressure within the pipeline.
Low Head Sealing: Designed for low head sealing, making it effective even where line pressures are generally lower than normal 3 psi (21 kPa) and lower.
High-Quality Materials: Available with a fusion-bonded ductile iron body as well as 304 or 316 stainless steel body, ensuring durability and corrosion resistance.
Surge and Water Hammer Protection: The valve provides effective surge and water hammer protection, reducing the risk of pipeline bursts and ensuring smooth operation.

The VENT-O-MAT Series RGXII “Anti-Surge” Sewage Air Release and Vacuum Break Valves are designed to handle nominal sizes ranging from DN50 (2″) to DN200 (8″). They are available in two pressure ratings: PN10 (150 psi) and PN16 (232 psi), ensuring reliable performance across various pipeline applications. The valve inlet and outlet sizes include DN50, DN80, DN100, DN150, and DN200.
